The Sheldon Conundrum

"The Big Bang Theory updated itself by making its protagonists into physicists and tossing in wheezes like the spherical cow joke—the kind of in-joke that only a science audience would even get. The tangles of equations on Sheldon and Leonard's apartment whiteboard are an actual ongoing problem written for the show by a UCLA physics professor, and there's talk of Nobel physicist George Smoot making a cameo on the show. It's a series laughing with geeks, not at them—and it's humor that finds its perfect vehicle in the geekiest of neurological conditions."

Paul Collins in Slate wonders if The Big Bang Theory's Sheldon Cooper has Asperger Syndrome.
